Analysis of polymer materials by surface NMR via the MOUSE.
Applications are discussed of a novel NMR device, the NMR MOUSE (mobile universal surface explorer), for characterization of polymers. Different properties of elastomers can be related to an effective transverse relaxation parameter T2eff. Effects of multi-echo sequences influence the decay curve and can be described in terms of B0 inhomogeneity and spin-lock effects. Furthermore, the signal-to-noise ratio (SIN) can be improved by use of steady-state free precession (SSFP) pulse sequences modified for use in inhomogeneous magnetic fields.
